| /** |
| * A type implemented by the Provider Role. |
| * |
| * <p> |
| * A non-binary compatible change to a provider type normally requires |
| * incrementing the minor version of the type's package. This change will |
| * require all providers to be updated to handle the change, but consumers of |
| * that package will not require changes since they only use, and do not |
| * implement, the provider type. |
| * |
| * <p> |
| * A type can be marked {@link ConsumerType} or {@link ProviderType} but not |
| * both. A type is assumed to be {@link ConsumerType} if it is not marked either |
| * {@link ConsumerType} or {@link ProviderType}. |
| * |
| * <p> |
| * This annotation is not retained at runtime. It is for use by tools to |
| * understand the semantic version of a package. When a bundle implements a |
| * provider type from an imported package, then the bundle's import range for |
| * that package must require the package's exact major and minor version. |
